1 Protegrin-1 inhibits porcine ovarian granulosa cell apoptosis from H2O2-induced oxidative stress via the PERK/eIF2alpha/CHOP signaling pathway in vitro. Hydrogen Peroxide eukaryotic translation initiation factor 2A Homo sapiens
2 Using Western blot analysis, it was found that PG-1 decreased the phosphorylation of RNA-like endoplasmic reticulum kinase (PERK) and the alpha-subunit of eukaryotic initiation factor 2 (eIF2alpha) as well as the protein expression level of CCAAT enhancer-binding protein homologous protein (CHOP), all of which were increased by H2O2. Hydrogen Peroxide eukaryotic translation initiation factor 2A Homo sapiens
3 Moreover, inhibitors against PERK and phospho-eIF2alpha both suppressed the H2O2-induced granulosa cells apoptosis and enhanced the anti-apoptosis effect of PG-1. Hydrogen Peroxide eukaryotic translation initiation factor 2A Homo sapiens
